I now have an Asus GTX 750 Ti card. It's now 4 months after I bought it, and it still doesn't work. The first two months, I didn't have the right type of power cable ready. The third month, I found that the VGA output was disabled at initial startup, so my monitor wouldn't allow me to see anything. I then found a DVI-D connector on my monitor, so I ordered a DVI-D cable. The fourth month, it would display a picture for about one minute on bootup, then go black, but would ignore the keyboard input needed to make the bootup proceed, so I suspect that it somehow stopped the bootup from reaching the point where the keyboard could be used.

Asus provides a number to call for graphics board problems, but not a toll-free number, so I'm likely to have a significant next telephone bill (perhaps two hours on hold).

Their technical support department insists that their GTX 750 Ti uses far more power than the Nvidia specs call far - 350 watts compared to 60 watts, and therefore need a power supply with a greater wattage than the Nvidia specs call for to run the whole computer (650 compared to 300). My computer room doesn't have that much extra power available; it's probably already sometimes using more than enough to trip the circuit breaker if there was no time delay to smooth out the peaks. I've asked about running another circuit to my computer room; the circuit breaker panel has no room for another circuit breaker, so that's not reasonable.

I've already found two more users on Primegrid who've had severe problems using Asus boards.

How many other users here are having severe problems using Asus boards? How many are getting them to work well? Is the ratio of these two bad enough that we need to consider Asus boards about as bad as Dell computers?

What other brands of graphics boards work well? It looks like I'll have to buy another GTX 750 Ti card, but of a different brand, to get one of my computers doing GPU workunits again.

If you purchase hardware that you can't properly connect and it takes you two months to get a cable you really can't blame anyone for that.

Sorry, I can't really comment on this. The screen going black could mean there's insufficient power but it could as well be something else IMO.

That must have been some kind of misunderstanding. I'm sure they meant to recommend a PSU with 350 watts total. The GPU alone just can't draw that much power. That's impossible. You should be fine with a good 350W PSU, assuming nothing else is taking too much power. Myself, I'm running seven CPU cores and a MSI GTX750 (no Ti) with that no problem. A 300W PSU could be close depending on your individual hardware, especially if it's a cheap one.

I've only ever had problems with one graphics board. That was a Powercolor, and years ago. Everything else always worked fine for me, including Asus.

If you bought this card new then I would go to the shop and swap for a new one as it is still under warranty. Or they check and repair it if possible and if not give you a new one.

I have many hardware from ASUS including GPU's and everything did work immediately after I installed it. I think that ASUS can be considered as a very good brand. And that is also true for Dell, I run several Dell's without issues.

However my favorite brand is EVGA, and nowadays I only buy GPU, MOBO and PSU from EVGA, for replacements or new builds.

But your ASUS GTX750 should work, go back to the shop.

Is this the only gpu in the machine? Wndows has a very bad habit of disabling resources that it thinks aren't being used during startup, a gpu with no monitor attached is a good example of that. A simple "dummy plug" can fix that.
http://www.overclock.net/t/384733/the-30-second-dummy-plug A second option is to plug in a 2nd monitor during the startup process and then unplug it once windows is up and running.

Same problem I had, call an electrician you may be able to get double breakers that put two breakers in the same slot a single breaker is in right now. I ended up getting three new 20amp circuits for my basement pc's that way.

Buy yourself a "kill-a-watt" device, Walmart sells them for about 20 bucks US, and plug it into the wall and then plug your pc into it, this will tell you exactly how much wattage your pc is drawing. Remember though startup usually takes more wattage then the just running does. Most people upgrade their power supplies when they start gpu crunching as most pc makers put in the minimum wattage power supply they can get away with when they make a pc, it is cheaper and their profit margins are higher. There is no need to put in an 850 watt power supply for most people who will never need one if the pc is only drawing 235 watts as it comes off the line. Dell is notorious for this, they will put in a 125 watt power supply if the machine only draws 100 watts.

I have a gpu, or two, in almost all of my machinea and every one has had the power supply upgraded to a 750 or 850 watt one. Yes it's overkill, but you don't want to be pushing the power supply to it's limits when crunching 24/7/365 for 5 years or so. I run AMD 7970 gpu's and Nvidia 760 gpu's.

If there's a second GPU, it's on the motherboard and its video connector is well hidden. There's no motherboard slot suitable for adding any more. I don't have an extra monitor or room to add one.

I thought only AMD/ATI boards needed the dummy plug.

The electrician who came to do the estimate of how much it would cost to add a second circuit should have known if double breakers were available for that type of circuit breaker panel, even if I didn't know to ask.

Not needed - the UPS I use for that computer includes the equivalent. It says that the computer uses up to 170 watts when running BOINC on 7 CPU cores and barely using the previous graphics card, which probably needs heatsink cleaning, but the heatsink is unreachable. It's a GT 440, with Nvidia specs that say it can use 65 watts. When I let BOINC use that card, it used to work but now soon overheats.

The computer's from HP, so I assume they used an adequate power supply for the previous video card; the new video card uses 5 watts less. I'll consider upgrading the power supply if I can first get another circuit added. Probably only to 450 watts though, since HP provides a part number for a suitable 450 watt power supply, but no higher. The computer's frame doesn't leave enough room to use an GTX 760.

Can you remove the card and just blow it out well with a can of compressed air?

I'm not sure you need to stick with an HP brand power supply but that doesn't make alot of difference, except for cost, since you are case limited in your gpu options anyway. If you are unsure if another brand will work I would just stick with the known HP one that will fit.

Since you are still having problems with the gpu have you tried plugging in a different one, or even just a cheap one in the same slot and see if the pc boots up just fine? If so you probably should be calling for a warranty replacement and just end this. If not then it could be a motherboard problem and then you have bigger problems. The one other thing I would do is unplug everything you don't need to boot up the pc, the network cable, the printer if any, the cd/dvd, anything except the hard drive, gpu, mouse and keyboard just to see if it works then. If so start plugging things back in again, when the machine is off of course, restart and see what is causing your problems.

Do you have a power supply tester? It's possible the power supply isn't up to snuff anymore, have you blown it out lately too? Be extremely careful if you use a compressor to blow things out, it's very easy to over speed fans and stuff and make things worse, cans of compressed air are best.

I have six Asus GTX 750 Tis on a variety of Haswell Z87/Z97 motherboards (Gigabyte and Asrock), 2 cards per boards. They work great, and the part about needing a larger power supply is total nonsense, as has been mentioned above.

However, the black screen is another matter. I suspect a BIOS incompatibility there, especially if it is an older motherboard. If your motherboard has a BIOS update, then try it. Just buying a different brand of video card may not fix it.

Monitor attachment or dummy plug is not needed. I have several rigs with monitors only connected to the first (main) GPU, and the other GPU works just fine without.
This is under windows.

It's fairly easy to remove, and I have some cans of compressed something, so I may try that. I can't see where to aim it in the old card, though.

The main reason why I am thinking of sticking with an HP power supply is that I do not have sufficient information on how to choose some other power supply that will fit that case and is also compatible with that motherboard. Also, the computer room is too close to tripping its circuit breaker to really consider a power supply with a higher rating, unless I decide to stop running both my desktops at the same time.

It boots up just fine with the old GT 440, but that card easily overheats if I let BOINC use it. I don't have any other graphics cards that should work with a 300 watt power supply.

I do not have a power supply tester or a compressor.

Yesterday, I tested the new card in my other desktop, which has a 450 watt power supply. It booted and worked properly with light use; a GPU workunit already in progress on that computer was not at a point where I considered it reasonable to test the board for CUDA or OpenCL use.

Since it appears that my computer room will not allow both upgrading the power supply and continuing to use both desktops at once, I consider it best to ask about two other possibilities I've thought of before doing much.

1. The computer where the new board works uses a BIOS and runs 64-bit Windows Vista. The computer where it doesn't work uses a UEFI instead and runs 64-bit Windows 7. Does this have anything to do which which board should work and which shouldn't?

2. Each DVI-D connector is supposed to be able to run two monitors. If the initial startup of the Asus GTX 750 Ti turns on only one of them, perhaps one of the monitors uses only the half that is not turned on, but the other monitor uses the one that is turned on. Is this reasonable? I'm thinking of buying a longer DVI-D cable so I can try the equivalent of switching the monitors.

I've thought of running a separate electrical circuit to my computer room, using a separate circuit breaker. The circuit breaker panel does not have room for another circuit breaker, or I would already be arranging that.

My Haswell motherboards use a UEFI bios, so that in itself is not a problem. And I use Win7 64-bit on all my machines, so that isn't it either. However, I did have some stability problems (not a black screen fortunately) on my Gigabyte board when running two GTX 750 Tis until I updated to the latest BIOS, which is still listed as beta on their website. Whether that might be available for your PC is another matter.

Another brand of card might work, but it is hit or miss at that point. Good luck.

Thanks.

It's fairly easy to remove, and I have some cans of compressed something, so I may try that. I can't see where to aim it in the old card, though.

At all the edges of the card and any fans holes you see too, basically all around the card where you can get any air into it. If it has an onboard fan spin it too with the can of air, hopefully it spins up quickly and easily, do not keep it running at full speed for more than a few seconds though.

As for the rest I have not had any problems with the older or newer bios's, I also run Win7 64bit on most of my machines, with Win7 32bit running on a couple and Windows Home Server running on another couple. I run WHS because it is cheap and because I need a Server to 'take control' of my local ip addresses when I power up too many devices. My two Servers are essentially Boinc only machines that just crunch and manage stuff in the background. I will probably shut the oldest one down because of my newest machine, a 16 core pc running Win7 64 bit.

Another brand of card might work, but it is hit or miss at that point. Good luck.

Since it uses a UEFI instead of a BIOS, I'll look for an updated UEFI instead.

The terminology is a bit confusing, and I don't claim to be an expert. I think that you are correct that UEFI is not BIOS, but is the successor. However, in my Gigabyte Z87 motherboard manual, it refers to it as "BIOS" that can be booted into either the UEFI or Legacy mode, depending on the OS. I think that "Legacy" refers to BIOS used in Win7, and it is really only Windows 8 that uses UEFI mode. But whatever they call the firmware on your motherboard, and update might help, and so might a different video card, but there is unfortunately no guarantee.

If any of you have made a GTX 750 Ti card do GPUGRID workunits properly, what brand of GTX 750 Ti card did you use?

Rumor has it that the final version of Win10 will require a UEFI system, but the preview works just fine on my regular bios right now.

If any of you have made a GTX 750 Ti card do GPUGRID workunits properly, what brand of GTX 750 Ti card did you use?

I run 7 (PNY) GeForce GTX 750 Ti Graphics Card - 2GB, GDDR5, 5400 MHz
Great card; without needing any additional power.

Can any of you with both an Asus graphics card and a device for measuring the amount of power the whole computer uses let me know how much power the computer plus the Asus card uses when running some GPU workunit? I've thought of the possibility that the extra power requirement for the Asus cards could be only during bootup.

Running two GTX 750 Tis on a Gigabyte Z87 with a Haswell i7-4771 (two cores supporting the GPU, four cores on other BOINC projects and two cores free) draws about 234 watts from the wall. That is with a Gold 90+ percent efficient power supply. I don't think the startup current is the problem, or you would not see the initial screen at all; any surge would be less than a second or two.

I've now tried a second GTX 750 Ti, EVGA brand. It doesn't allow booting either, even though the EVGA specs say a 300 watt power supply is adequate.

The EVGA customer service department has a very different idea of what is going wrong, though - a BIOS that just won't handle booting with a GTX 750 Ti (any brand) installed. They pointed me to a site for downloading updates specific to this model of computer; I tried the BIOS update offered there and it made no difference.

I looked into returning the ASUS GTX 750 Ti; the online store only allows such returns within 30 days after buying them, and only for getting another board of the same model rather than returning the money.

I contacted HP, trying to get another BIOS update that allows it to boot with a GTX 750 Ti. The answer was that the motherboard of that computer is not compatible with any Nvidia-based graphics board more recent than a GTX 550i, which implies that I can no longer make that computer run GPUGRID GPU workunits.
